v1.2.16.10 ???????

how i can change game language? i tey to modifie the xml but nothing

Everytime I try to add the update I get "Hash Sum Mismatched"
How do I fix this?

I downloaded the Royalty & Legacy expansion posted February 13th. The game loads with that.
I tried to update it with this (Dragged the Game/Bin folders in like I normally do) and its giving a bunch of errors on the installer now and the game crashes on the loading screen.
So how to I do the updater?
